WESLEY J. BARRETT, OF MARION, NEW YORK.

INDICATOR IFQR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 661,482, dated November 13, 1900.

Application filed May 14, 1900. serial No. 16,646. (No model.)

To all whom, it may concern.-

Be it known that LWEsLEY J. BARRETT, of Marion, in the county of Vayne and State of New York, have invented a new and useful Improvement in Indicators for Bottles, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention relates to bottles generally, and particularly to the class known and understood as non-refillable bottles. This invention is not, strictly speaking, a non-refillablc bottle, but rather a bottle provided with a device placed within it and permanently attached to the bottom thereof to indicate the fact that the'bottle has been a second time filled, if such be the case. Thus a bottle supplied with this indicator, while not non-refillable, answers all the purposes of a non-refillable bottle.

The invention is hereinafter fully described and more particularly pointed out in the claims.

Referring to the drawings, Figure l is a side elevation of a bottle, showing the indicator attached in place, parts being broken away and sectioned as on the broken dotted line 1 1 in Fig. 2. Fig. 2 is a cross-section of the bottle on the dotted line in Fig. 1. Fig. 3 is a central longitudinal section of the indicator and adjacent part of the bottle, taken on the dotted line 3 in Fig. 2. Fig. 4 is a crosssection of the indicator on the dotted line in Fig. 3. Fig. 5 is a longitudinal section of a modification of the device, it being a simpler form of the indicator.

A is a glass bottle of any form or kind, B being the bottom.

0 is the indicating device or indicator, permanently secured to the inner face of the bottom of the bottle by any suitable means, as glass-cement. This indicator-body is of glass and consists of a cylindrical inclosing shell or, containing within it concentric tubes or cylinders b 0 (Z and surmounted by a glass bulb e, as shown. The inner tube or cylinder 17 is secured to the upper plate h of the indicator 0 and is open at both ends, the upper end communicating with the space within the bottle, the lower end being some distance above the base of the body 0. The middle tube or cylinder 0 is secured to the base of the body C and open at its upper end, above which there is space beneath the plate h of the shell. The outer cylinder cl is secured to the plate 71 and, reaching downward, has its lower open end some little distance above the base of the body 0. Thus arranged these inner cylinders graded as to size alternate and overlap each other, serving to divide the space Within the shell a into annular chambers or apartments. The air-bulb e is placed at one side of the body C, as shown, there being an opening f through the plate 7L, communicating between the space within the bulb and the outer annular space I of the body 0. The bulb is also formed with a small orifice or outflowopening g in its upper end, as shown.

The body 0 is preferably made larger in diameter than the internal diameter of the neck of the bottle and secured to place upon the bottom B of the bottle during the process of forming the latter and before the neck portion is completed.

\Vhen the bottle is originally filled, the liquid flows into the indicator and fills all the apartments therein and the air-bulb 6, excluding all air therefrom, the air escaping through the orifice g. After the bottle is filled the orifice g is filled and closed with glass-cement.

When the liquid with which the bottle was originally filled is turned out by inverting the bottle, the inrushing air will rise and occupy a part (more or less) of the space within the shell a, displacing a like part of the liquid. This body or bubble of air once within the shell cannot escape on account of the opening 9 being sealed, as stated, and remains imprisoned therein, and when the bottle is turned uprightas for the purpose of refilling, for examplethe bubble of air will ascend to the upper end of the bulb e and so immovably remain to indicate that the bottle has been a second time filled.

The indicator may be constructed as shown in longitudinal section in Fig. 5, this being a more simple and cheaper construction; but I prefer the form shown in the other figures as being more certain in action.

What I claim as my invention is- 1. An indicator for bottles, consisting of a hollow body rigidly fixed within the bottle, and concentric cylinders in the hollow body dividing its space, the inner cylinder opening into the space within the bottle, substantially as specified.

2. An indicator for bottles, consisting of a hollow body within the bottle, having its inclosed space divided into annular chambers by graded overlapping cylinders, with an airbulb communicating with the outer chamber, and an outflow-opening in the air-bulb, substantially as set forth.

3. An indicator for bottles consisting of a hollow body Within the bottle and hollow parts in said body dividing the space within it, and a bulb secured to said body, the latter with the contained parts and the bulb being made of transparent material, substantially as specified.

4. An indicator for bottles, consisting of a hollow cylindrical body in the bottle, having its interior divided by graded overlapping cylinders secured alternately to the upper wall and to the base of the body, substan tially as and for the purpose specified.

5. An indicator for bottles, consisting of a body secured to the inner surface of the bottom of the bottle, and divided internally into a series of chambers from the middle outward, and a tube or bulb open at both ends projecting from said body and communicating with the outer chamber of the body, there being a continuous passage from the interior of the bottle through said series of chambers and outward through said tube or bulb, sub stantially as shown.

In witness whereof I have hereunto set my hand, this llth day of May, 1900, in the presence of two subscribing witnesses.

WESLEY J. BARRETT.
